Subject: [GIT PULL] cpupower update for Linux 6.4-rc3

Hi Rafael,

Please pull the following cpupower update for Linux 6.4-rc3 or for
a later rc.

This cpupower fixes update for Linux 6.4-rc3 consists of:

- a resource leak fix
- fix drift in C0 percentage calculation due to System-wide TSC read.
   To lower this drift read TSC per CPU and also just after mperf read.
   This technique improves C0 percentage calculation in Mperf monitor

diff is attached.

thanks,
-- Shuah
